FEED-WATER FILTER AND PURIFIER.

Application filed September 1, 1908.

Specification of Letters Patent.

T 0 all whom it may concern:

Be it known that 1, 1mm: Gr. COPELAND, a citizen of the United States,residing at- Portland, county of Multnomah, and State of Oregon, haveinvented certain new and useful Improvements in Feedater Filters andPurifiers, of which the following is a specification.

This invention relates to feed water filters and purifiers.

The object of the present invention is the provision of a filter andpurifier especially adapted for purification of water intended to beused in steam boilers, although not restricted to such use, which willembrace novel means for supplying a precipitating material to thefiltering chambers, novel means for catching the material from the waterbeing purified, novel means for agitating and heating the water belowits level or surface, and novel means for agitating the surface of thewater undergoing purification, novel filtering media, all adapted toefficaciously and readily filter and purify the water and permit rapidand easy fiushing of the filter when necessary.

The invention is set forth fully hereinafter and the novel features arerecited in the appended claims.

In the accompanying drawings: Figure 1 is a side elevation, principallyin section; Fig. 2, a plan view; and Fig. 3, a section on line 3-3 ofFigs. 1 and 2.

The shell or casing 1 of the filter and purifier is divided into anumber of compartments or chambers 2 which are defined by partitions 3each having an opening 4 braced by an angle iron framing P, thepartitions being braced and connected to the casing 1 by an angle ironframing 1. Secured to the opposite side of each partition is achannel-iron framing 5 in which is re movably seated a frame 5 having ascreen 6, and a filtering material 7 of some such suitable fabric burlapor its equivalent, both riveted to frame 5 by rivets S. The frames 5 areremovable for purposes of repair when necessary. The screens will notrequire removal as often as the material 7, which requires renewal whenit becomes damaged or clogged. The frames 5 are slid vertically in thechannel irons 5 and out through openings 1 closed by doors 1 in the topof easing 1 when renewal or cleansing becomes necessary. The rivets Sare cut when removing the screens or filtering material from theirframes 5.

The entrance end of the filter and purifier is divided into two chambers9 and 10 by a partition 11 which stops considerably short of the top ofthe casing or shell 1 and over which the 'ater flows from chamber 9 tochamber 10. The water to be filtered enters chamber 9 in the lower partthereof through a pipe 12 and exhaust steam enters through a pipe 13,having a suitable controlling valve 14:, by which the water is heated.

There is a hopper or box 15 having suitable means for access to itsinterior, which is adapted to contain a liquid precipitating compound orchemical, according tothe character of the water to be purified andfiltered, a pipe 16 leading from this hopper and being adapted todischarge into the lower part of the chamber 9, the feed beingcontrolled by a valve 17. The liquid chemical or compound gives aninitial precipitation supplemented by the heat of the exhaust steam,which eliminates the greater part of the foreign matter from the water.Each chamber is provided with a mud drum or sediment collector 18 at itsbottom, said collectors being inclined from one end to the othertransversely of the entire filter as shown in Fig. 3 so that thesediment will more readily pass out and to this end there is provided apipe 19 which has valved connections 20 with the respective mud drumsThe exit pipe is shown at 21.

On one side of the filter near the top thereof is an over-flow pipe 22having branches 23 connecting with the respective chambers and on theopposite side is a steam pipe 24 having branches 25 connecting with therespective chambers, the relation of the pipes 22, 23, 24:, 25, beingsuch that the steam entering the chambers agitates the surface of thewater and blows to the overflow pipe the lighter particles of sedimentand scale which are then taken through by the over-flow, the heavierparticles falling into the mud drums where they are collected andsubsequently removed by flushing. The water which finally reaches theoutlet pipe 21 is thoroughly purified and filtered.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is 1. In a filter and purifier, the combinationwith a chamber for the passage of the water, and a filtering mediumcontained within said filter, of means for introducing steamsubstantially at the water line for agitating the surface of the water.

2. In a filter and purifier, the combination with a chamber for thepassage of the water, and a filtering medium contained within saidfilter, of means for introducing steam substantially at the water linefor agitating the surface of the water and take-off outletssubstantially at the water line for removing the particles on thesurface of the water.

3. In a filter and purifier, the combination with a chamber, and afiltering medium contained within said filter of means for introducingsteam or the like substantially at the surface of the water, in thechamber, and an over-flow and take-off disposed opposite the said means,whereby the particles are blown from the surface of the water andremoved.

4. In a filter and purifier, the combination with a chamber havingpartitions disposed at intervals lengthwise thereof, sub-dividing thesaid chamber into a plurality of independent compartments, independentfiltering media carried by the respective partitions pipes leading tothe respective compartments substantially at the surface of the waterfor introducing steam or the like, a source of supply for said pipes,and independent take-off pipes disposed opposite the said inlet pipes,whereby the particles are blown from the surface of the water in therespective compartments.

In testimony whereof, I hereunto afiiX my signature in presence of twowitnesses.
